Dyes used in fluorescence microscopy
WebThe basicpremise of fluorescence microscopy is to stain the components with dyes. Fluorescent dyes (fluorophores) which consist of molecules that absorb excitation light at a given wavelength (generally UV), and after a short delay emit light at a longer wavelength. The delay between absorption and emission is negligible, generally WebIn immunohistology and immunocytology, fluorescein-5-isothiocyanate (FITC) serves as a fluorescent marker for microscopic visualization and detection of tissue-bound bio molecules such as antigens, lectins, proteins, peptides, nucleic acids, oligo- and …
